557A to Stepper
« on: May 10, 2011, 03:50:51 PM »
Hi All;
Thank you to everyone who has helped me with the 557 and the stepper system...  I have the 557A working just fine.. And am working on getting the stepper going as well... My question is since the 557A is a 24volt system and the stepper is a 48-52 volt system, will it be a problem to hook up the 6 phones to the 557A and to the stepper as well, so that they can be hooked up manually with the 557A or Dialed with the stepper ??
